Title: Improvements relating to cutting and slicing machines
IPC: B26B29/06
Filed: 1922-10-27
Abstract: 206,009. Kirtley, G. H. Oct. 27, 1922. Saw guides.-In a slicing-machine of the type wherein a hand-knife is operated between vertical guides situated at one end of the loaf-supporting table, an adjustable gauge-plate is pivotally mounted so that the knife in its descent presses the gauge-plate beneath the table and allows the severed slice to fall. The table a supports guides c, spaced by a bar d, and the knife f is limited in its movement by a stop h at one end and a similar stop, or the handle, at the other end. The gauge-plate is mounted on a cranked rod j carrying a roller q which engages the knife which moves the plate against the action of the spring p. The gauge plate is adjustable for slicethickness by sliding the hinge l in the bearing m and clamping with a screw o. The loaf may be fed forward mechanically.

Title: Improvements in the folding of paper
Inventor: KEMP JACK VOYNA LESLIE
IPC: B65H45/00
Filed: 1957-09-20
Abstract: 848,234. Folding paper. KEMP APPLICATIONS Ltd. Sept. 12, 1958 [Sept. 20, 1957], No. 29666/57. Class 100(1) A folding machine comprises means for feeding single sheets of paper to a folding mechanism which makes an initial fold in each sheet with a sharp crease extending along most of the length of the fold and the remainder of the fold at one end of the sheet being increased, and a conveyer which moves the sheet from the folding mechanism past a guide which folds the two ends of the sheet towards each other along folds at right angles to the initial fold with the result that one end of the sheet, where the initial fold is creased, is brought adjacent to the other end of the sheet where the initial fold is increased and the one end of the sheet is inserted between the parts of the sheet at its other end. The pile of sheets rests on an inclined tray 9 and a roller 11 separates single sheets from the pile and feeds them between rollers 13, 14 of a buckle plate folding device. The front end of the sheet slides up a plate 16 until it encounters an adjustable stop 17 thereon and thus causes the sheet to. be buckled into the nip of the roller 14 and another roller 15 which extends from one end of the roller 14 to a position short of the other end. The transverse fold produced in the sheet is therefore sharply creased only along a length corresponding to the length of the roller 15, a portion thereof at one end remaining uncreased. After passing between the rollers 14, 15 the folded sheet falls on to an endless conveyer 18 which carries it to the right as shown in Fig. 2, the sheet lying slightly askew on the conveyer owing to the action of a deflector 59 fixed' to the plate 16 and which engages the creased end of the folded sheet as it passes on to the conveyer. The ends of the sheet overlie metal strips 53, 54 fixed to a table portion 3 of the machine while the middle of the sheet is pressed down on to the conveyer by a series of rubber rollers 55 carried in a casing 56. The strips 53, 54 incline upwards so that as the sheet is advanced by the conveyer the ends thereof are bent up vertically round the sides of the casing 56. The creased bent-up end then passes between guide plates 62, 63 which fold it over inwards towards the centre-line of the conveyer. Simultaneously the increased end is also folded inwards by the inclined edge 64 of a guide plate 65. As the ends are folded inwards the creased end engages between the two sides of the folded sheet at its increased end, Fig. 9. The sheet is then pressed flat beneath inclined strips 66, 67, 68 and all the folds are sharply creased as it passes beneath a roller 24 which co-operates with a roller 20 that supports one end of the conveyer 18. The folded sheets are finally delivered on to a second conveyer 25 which stacks them against an inclined plate 33. The separator and buckle folding rollers and the conveyers are driven from an electric motor 34.

Title: Improvements in or relating to the simultaneous reproduction of sounds and pictures
Filed: 1927-11-08
Abstract: 305,617. Mittell, B. E. G., and Gramophone Co., Ltd. Nov. 8, 1927. Sound - reproducing apparatus associated with kinematographs.-In the simultaneous reproduction of pictures and sound, provision is made for reproducing the sound of higher frequencies so as to locate this sound on the screen adjacent to the position of the apparent source, in the picture, of that sound. The pictures may be projected on to the front of the screen or, as shown, through a window 3 in a horn 1 on to the back of a translucent screen 4 mounted in the horn mouth. The horn 1 is adapted to reproduce mainly the lower frequencies, and a number of reproducers 5, 6 are positioned to reproduce the higher frequencies at different positions on the screen and controlled manually or automatically so as to be operative when the apparent source of the sound in the picture is in the position in the picture served by that reproducer. The high frequency reproducers are operated through switches controlled manually or automatically by holes provided and positioned in the picture film to operate pneumatically as in a piano-player or by photographic markings on the film acting on a light-sensitive device. When controlled by holes on the film the holes may be hand cut or produced automatically during the production of the combined picture and sound record, the cutting mechanism being controlled by a device sensitive to the direction from which sound falls upon it. Similarly, when controlled by markings on the film those markings are produced by a device sensitive to tne direction of the sound during optical recording of the sound on the film. Alternatively, the several high frequency reproducers may be replaced by one or more movable ones whose position can be varied as required either manually or automatically. When the picture screen is arranged in a flared proscenium opening in a theatre this opening may constitute the mouth of the main horn.

Abstract: 891,804. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Sept. 2, 1960 [Sept. 4, 1959], No. 30261/59. Drawings to Specification. Class 39(4) A method of operating a gas cooled nuclear reactor provided with fuel element leak detector apparatus for detecting short-lived fission products, comprises reducing the pressure in the coolant circuit while the reactor is operating at power so that fission products are forced through any existing leaks in the fuel element sheaths into the coolant stream for detection by the leak detector apparatus. As an example, starting with a de-pressurised shut-down reactor the reactor is brought to normal working pressure of 90 p.s.i.g., the power raised to 5MW, and readings are taken on the leak detector for all channels; the reactor coolant gas is then blown off to a pressure of 20 p.s.i.g. over a period sufficient to allow the reactor to be scanned twice over by the leak detector apparatus, say about 40 minutes. Specification 867,368 is referred to.

Abstract: 1,087,405. Resistors. SOCIETE GERAFIN S.A. July 16, 1965 [July 28, 1964], No. 30302/65. Heading H1S. A number of resistors are formed by covering a first face of a long insulating support plate with conductive material, depositing on part of the other face a layer 3 of semi-conductive material (graphite) and continuing it into contact with the conductive material on the first face, providing pairs of holes 5 to hold terminal members 6 and cutting through the support plate between alternate terminals. The terminal members 6 are soldered to the conductive covering which is etched or cut through between them so they are connected each through a remaining strip of heat dissipating covering (2a, 2b, Fig. 1, not shown) to different parts of the semi-conductive layer 3. Each resistor is adjusted to a required value by removing semiconductive material until its value corresponds to that of a reference resistor. The semi-conductive material may be deposited by sputtering or dipping. Its connection to the conductive coating may be supplemented by a varnish with a silver base. The terminal members may be formed from a metal band 8. The resistor may be protected by varnish and " colour coded."

Abstract: 1,186,983. Inking apparatus. PLAMAG PLAUENER DRUCKMASCHINENWERK. 26 June, 1968, No. 30398/68. Heading B6C. In inking apparatus forming part of a rotary printing machine adaptable for both multicolour and single-colour working the stroke of longitudinally reciprocated inking rollers is changed between higher and lower values. Connecting rods 1, 2 are mounted on eccentrically bored bush 3, and bush 3 may be rotated anywhere between a first position in which its eccentricity e 2  and the eccentricity e 1  of eccentrically mounted member 4 relative to drive shaft 5 are additive and a second position in which the eccentricities are opposed. Bush 3 is rotated by spindle 16 through gears 17, 15, 14 and 13. Sleeve 19 surrounds spindle 16, and a pin in spindle 16 co-operates with a slot in sleeve 19 to limit their relative rotation to 180 degrees. Spindle 16 is turned by box spanner 33 and the bevelled periphery of spanner 33 and the bevelled periphery of spanner 33 actuates safety switch 34, causing clutches 11, 12 to engage and clutch 18 to disengage. Shaft 5 is in consequence locked to halted drive shaft 8 and sleeve 19 becomes rotatable relative to spindle 16. Engaged gears 20, 5 cause relative rotation of spindle 16 and sleeve 19 by 180 degrees to result in rotation of bush 3 against member 4 through the same angle. The speed of reciprocation of the rollers may be determined by gears 6, 9 or by gears 7, 10, according to whether clutch 11 or clutch 12 is engaged. Alternatively mechanically engaged gears may be employed in place of clutches.

Abstract: 732,527. Electric telemetering systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 4, 1953 [Nov. 6, 1952], No. 30437/53. Class 40 (1).  A measuring current is transmitted to a remote receiver through a pair of lines via relays at each end so that a power measurement can be simultaneously transmitted over the same lines in the form of a series of pulses by reversing the current direction in the lines for the duration of each pulse, to operate a relay at the receiving end which feeds a pulse counter, the impulse transmission being unaffected by faults at the transmitting end. As shown, the measuring circuit is prepared by applying at the transmitter A an auxiliary voltage E to produce a current through the transmission lines 1, 2 which energizes a relay FR at the transmitter A and a relay MR at the receiver B. Operation of relay FR causes the measuring current from meter MG to flow through a relay FRH, whereupon two contacts transfer the energization of relay FRH from the transmitter MG to the auxiliary voltage E, and a further two contacts transfer the lines 1, 2 from the voltage E to the transmitter MG, the measuring current in the lines being sufficient to hold relays FR and MR, and being indicated on a meter I at the receiver B, which is fed through a bridge rectifier L so that its reading is independent of the direction of the current in the lines 1, 2. When a power measuring pulse is sent from pulse transmitter IS, a relay SR is energized to reverse the direction of the line current, whereupon relay MR closes its back contacts to energize a relay HR, and affect a pulse receiver IM, e.g. a pulse counter. The line current reverts to its normal direction at the end of the pulse. Fault indications.-If the measuring current falls below its normal zero level, relays FR and MR fall, followed by relays FRH and KR, the latter closing an alarm circuit, and the former re-establishing the impulse signalling circuit. by connecting the lines 1, 2 to the'auxiliary voltage E. If the fault is in the transmitter MG manual resetting of relay KR will cause it to hold, but if the fault is in the transmission lines relay KR will not hold since relay MR is unenergized.

Abstract: 1465731 Hay baling apparatus CHROMALLOY AMERICAN CORP 9 July 1974 [19 Oct 1973] 30438/74 Heading A1F A hay baling apparatus consists of a wheeled frame defining a baling chamber open at the bottom and arranged to form a cylindrical bale by rolling hay up from the ground. An endless raking member 32, consisting of roller chains 33 connected by raddles 34 with hay engaging elements 34b is trained around lower rear sprockets 22, front sprockets 24 and upper sprockets 31 and moves counterclockwise, having a lower run in the baling chamber between the rear and front sprockets. Sets of elongated tines 43 are fast with cross shafts 42 mounted within the cylinder of rotation of the lower rear sprockets 22 and rotate therewith. Each cross shaft is caused to oscillate by means of crank arms 45 and cam followers 46 running in cam tracks 49 eccentric to the sprocket axis. The sets of tines penetrate the swath of hay as they swing around the bottom of the cylinder of rotation of the sprockets and start to roll the hay forward and upward at a speed greater than that of the hay engaging elements 34b the lower run of the raking member 32 moves to form a curve around the bale operating against the action of springs 27 bearing pivoting arms 25. Since the tines are withdrawn from the rolling hay very early in the action of the hay engaging elements on the hay, any tendency of the tines to loosen the hay is overcome by the operation of the raddles.
